DAVID J. PRYOR, OF BOSTON, MASSACHUSETTS.

HORSESHOE.

SPECIFICATION forming part of Letters Patent No. 346,497, dated August 3, 1886.

Application filed March 22, 1886. Serial No. 196,081.

To aZZ whom it may concern.-

Be it known that I,D.Wr1) J. PRYOR, a citizen of the United States, residing at Boston, in the county of Suffolk, State of Massachusetts, have invented certain new and useful Improvements in Horseshoes, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to improvements in horseshoes, and has for its objects to provide a shoe which will wear longer than those in ordinary use, shall be more easily applied, shall prevent the formation of snow-balls in the frog of the animals foot, and also relieve the hoof from the usual jar when the animal is driven over hard ground. These objects are attained by the devices illustrated in the accompanying drawings, forming apart of this specification, in which Figure 1 is a side elevation of a shoe attached to a horses hoof. Fig. 2 is asectional view taken on the line as :v of Fig. 3. Fig. 3 is a plan. Fig. 4 is a view taken from the under side of the shoe. Figs. 6, 7 are detached front views of plates A and O.

The letter A is the shoe proper, and has a series of nail-holes, a, to receive the nails, whereby it is secured to the horses foot, and is also provided with slots B at the heel, and openings I) b and lug b at the toe. The opening Z) is intended to engage with a lug, 0, forming part of the lower plate, 0, and the opening 2) is intended to receive the bolt E,which passes through an opening in the lug c. The bolt E may be screw-threaded or be provided with any other suitable means to maintain it in place when inserted in the above described openings. The lug I) is intended to enter a recess, Z,'in the upper side of the lower plate, 0, and serves the purpose of giving additional security in holding theshoeproper and the lower plate, 0, together, and at the same time strengthens this portion of the shoe proper and permits a larger bolt, E, to be used. The lower plate, 0, is provided with lugs D, which have in the rear an inclined backwardly projecting surface, d, adapted to engage with an inclined surface, 6, in the slots 13, which these lugs D are intended to enter, and which draw the upper (No model.)

plate, A, and lower plate, 0, forcibly toward each other when the bolt E is screwed up to its seat, and completes the fastenlng of these plates to each other. On its under side the plate 0 is provided with a toe-calk, F, and heel calks, G, and between the calks F and G, on both sides of the plate 0, are a series of small calks, H, of pointed form, which are intended to engage with the ground when the under surface of the ealks F and G have worn down sufficiently to permit it. A metal plate, I, having a recess, t, on its upper surface to permit the frog of the animals foot to enter, and having its outer contour beveled down to a sharp edge, is placed between the upper plate, A, and lower plate, 0. A washer, K, of leather, gum, or other elastic material is intended to be placed be tween the plate I and lower plate, 0, and is to serve the purpose of a cushion, and thereby prevent the jar to the animals hoofs when traveling over hard ground, which would otherwise occur.

It will be observed that the shoe proper, (or upper plate,) A, extends on each side beyond the outside of the lower plate, 0, so that the nail-holes a are exposed to view. The object of this construction is to permit the shoe Ato be nailed to the hoof without removing the lower plate, 0.

This shoe is to be used for horses or mules, with or without ealks.

Having described my invention, what I desire to secure by Letters Patent and claim 1sl. A horseshoe consisting of the shoe proper, A, provided with slots B, openings 1) Z), and lug b, in combination with plate 0, having lugs c and D on its upper side and on its lower side, the toe-call; E, heel-calks G, and series of small calks H, and bolt E, as described, and for the purposes set forth.

2. In a horseshoe, the upper shoe proper, A, the plate I, having recess 6, the washer K, and the lower plate, 0, having toe-call:
